You can specify an arpeggio sign on a chord by attaching an
\arpeggio to a chord:
<c e g c>\arpeggio
When an arpeggio crosses staves, you attach an arpeggio to the chords
in both staves, and set
PianoStaff.connectArpeggios:
\context PianoStaff <<
\property PianoStaff.connectArpeggios = ##t
\new Staff { <c' e g c>\arpeggio }
\new Staff { \clef bass <c,, e g>\arpeggio }
>>
The direction of the arpeggio is sometimes denoted by adding an
arrowhead to the wiggly line. This can be typeset by setting
arpeggio-direction:
\context Voice {
\property Voice.Arpeggio \set #'arpeggio-direction = #1
<c e g c>\arpeggio
\property Voice.Arpeggio \set #'arpeggio-direction = #-1
<c e g c>\arpeggio
}
A square bracket on the left indicates that the player should not
arpeggiate the chord. To draw these brackets, set the
molecule-callback property of Arpeggio or
PianoStaff.Arpeggio objects to \arpeggioBracket, and use
\arpeggio statements within the chords as before:
\property PianoStaff.Arpeggio \override
#'molecule-callback = \arpeggioBracket
<c' e g c>\arpeggio
\arpeggioBracket,
\arpeggio.
It is not possible to mix connected arpeggios and unconnected arpeggios in one PianoStaff at the same time.
